T0 at whom, it may concern:

Be it known that I, J OSEPH V7. CRAMER, a citizen of the United States, residing in Kan sas City, in the county of W yandotte and the State of Kansas, have invented new and useful Improvements in Safes, of which the following is a specification.

My invention relates to improvements in safes. It relates particularly to the locking mechanism connected with the door.

The object of my invention is to provide a safe-door-locking mechanism which is easily operated, has great strength, is durable, and located so that access to the bolts cannot be had from outside when the door is closed.

The novel features of my invention are hereinafter fully described and claimed.

Figure 1 is a view showing a portion of a safe in side elevation, the door being shown swung to the open position so that the rear side is presented to view, the motor and timeactuated mechanism controlling the motor being removed. Fig. 2 is a vertical cross-section taken in a plane corresponding to the dotted line 6 f on Fig. 3. In this view the bolts are shown in solid lines in the retracted position and in dotted lines in the extended position. Fig. 3 is a horizontal sectional view taken on a plane corresponding to the dotted line a b of Fig. 2. In this view a portion of the safe, the door, and the two casings containing the motor and the time-actuated mechanism are shown, the door being shown in the closed position and the bolts shown in solid lines in retracted positions, the extended position of the bolts being represented in dotted lines. Fig. 4 is a rear elevation view of the casings containing the time-actuated mechanism and the motor for retracting the bolts. Fig. 5 is a rear elevation view'of a modified form of my invention in which the bolts are retracted and extended by means of a rock-bar extending through the door to the forward side thereof. Fig. 6 is a vertical sectional view taken on the dotted line 0 d of Fig. 5.

Similar characters of reference denote similar parts.

1 denotes the body of the safe, having a circular opening with a bevel-seat 2, to which is fitted the beveled body of the safe-door 3, pivotally mounted at its upper and lower ends between the two arms of a vertical bracket 1, which is hinged to the safe-body.

cylindrical flange 5, provided adjacent the bevel portion of the door with an annular peripheral groove 6. Upon the rear side of the door 3 are mounted a plurality of radial U- shaped guides 7, in which are radially slidable a plurallty of bolts 8, 9, and 10, respectively. The bolts 8, 9, and 10 extend through radial slots in the flange 5 and into the annular groove 6. Each of said bolts-is provided at its outer end with an arcuate head 11, fitted in the annular groove 6, and when the bolts are retracted, as shown in Figs. 2 and 3, forming a circular divided ring.

The radial throw or movement of the bolts 8, 9, and 10 is such that when the bolts are extended the heads 11 lie partly within the groove 6 and overlap the inner side of the body of the safe, as shown in dotted lines in Figs. 2 and 3. Whenthe bolts are retracted, the heads 11 lie wholly within the groove 6, us permitting the door to be opened. Pivoted to the rear side of? the door between the bolts 8 and 9 and between the bolts 8 and 10 are two levers 12 and 13, the opposite ends of the lever 12 being pivoted to the adjacent bolts 8 and 9, and the opposite ends of the lever 13 are pivoted,respectively, to the adjacent bolts 8 and 10. The said leve1s12 and 13 are so positioned that when the bolt 8 is radially moved the said levers will be swung so as to similarly move the bolts 9 and 10 that is, when the bolt 8 is outwardly moved the levers 12 and 13 will be swung so as to move outwardly the bolts 9 and 10.

When it is desired to have the bolts retracted by a time-controlled motor, the following mechanism is provided: Pivoted to the rear side of the door is a lever 14, one end of which extends through the guide 7 and is pivoted to the bolt 8. The other end of the lever has mounted thereon a rearwardlyeextending stud 15, reciprocated by a motor of any suitable construction contained in a casing 16, suitably sup-ported upon the rear side of the door 3 and controlled in its operation by a time-lock mechanism of any suitable construction and contained in a casing 17, also supported upon the rear side of the door. I do not confine myself to any particular style of motor or time-lock mechanism, as any of the ordinary kinds commonly used will answer. The function of the motor is to move the stud 15 at the time the time-actuated mechanism permits and force the said stud and lever 14 from the position shown in solid lines to that shown in dotted lines in Fig. 2. When the lever 14 is so swung, the bolts 8, 9, and lOare retracted.

In Figs. 5 and 6 I have shown a'l orm of my invention in which the bolts may be operated from the outside. In this form of my invention a rock-shaft- 18 extends through the door 3, the-forward end of the shalt being squared to permit of being gripped with a crank-wrench, (not shown,) by means of which the shalt is rocked. To the rearend oi the shalt-18 is rigidly secured one end of a crank-arm 19, the OtlGl end of which extends ti'irough the adjacent guide 7 and is pivotally connected to the bolt 8. By rocking thesaalt 18 to and fro the bolt 8 is radially moved, thus radially moving the bolts-9 and 10 by means of the levers 12 and 13.

Having thus described my invention, what I claim, anddesire to secure by Letteis Patent, is

1. The combination with a safe-door oi circular shape having an annular peripheral groove, oi two bolts radially movable on the door and extending into said groove, each bolt having at its. outer end an arcuate head fitted in said groove, a lever pivoted to the door and pivotally connected at opposite ends to said bolts, he disposition of said lever relative to said bolts being such that when one bolt. is radially moved outwardly the other bolt will be moved in a like direc tion, and means for moving one of said bolts radially.
